What is a plant watering globe? The complete guide for beginners

A watering globe is a simple but ingenious tool for anyone who loves plants but isn't always home to water them. You push the globe into the soil of your pot, fill it with water, and it slowly releases moisture to the roots of your plant at exactly the right moment. No technology, no electricity, no hassle. It is the smartest way of watering plants without having to think about it every day.

How does a watering globe work exactly?

The way a watering globe for plants works is based on capillary action and soil pressure. When the soil dries out, a slight vacuum forms that pulls water out of the globe. Is the soil still moist enough? Then the globe stops automatically. This makes it a fully automatic watering system for plants without electricity or technology. Want to dive deeper?
